Here's a great drill I found on YouTube.
The rope has a knot tied on the end of it and that serves as the 'clubhead.' Here's some pics of it in action.
If you can lag a nylon rope, you can lag a steel or graphite golf shaft.
However, this drill looks like it requires a 'straight line delivery path.' Pic of Aaron Baddely below:
As discussed before the red line is Aaron's hand delivery. This is called a 'straight line delivery path' because his hands are initially go towards the ball in the downswing in a straight line. It then makes a 'U' pattern.
Anthony Kim is an example of a 'circular delivery path.'
With the rope drill, I think it's geared much more towards the straight line delivery path. There could be a way to do it with a circular delivery path, but it would seem very hard. That also indicates it's a drill meant more for the 'hitter' than the 'swinger.' Although I do think a swinger could pull it off.
In my next post I will look at the 'aiming point' concept that Mr. Kelley wrote about in 'The Golfing Machine.'
